According to my anatomy and physiology of farm animals class, regions and systems are two different things. Often mistakenly used.
Regions are all the components in a section of an animal- the blood vessels, tissues, nerves, cells, bones, etc. IN THAT SECTION (imagine dividing the animal into parts).
Systems overlap regions and refer to the networksinside the body as a whole- skeletal, muscular, integumentary, immune, nervous, digestive, cardiovascular, respiratory, sensory, endocrine, urinary, reproductive, etc.
If your professor asks you to list the components in the cervical region of a canine, you would list all the above components in said region. If your professor asks you which system bones and joints belong to (for example), you would say the [skeletal] system. Make sense?
